Hi,

I upgrade from Kubuntu 20.04 to 20.10 few days ago and since i have a weird behavior with my keyboard.
While most of the time keyboard works well, there are some places where it looks like not working.

For example, i have as main menu applet "Application menu" and if i want to search an app by typing few letter in searchbox, nothing appears. I mean i type but no letter appears.

If i open a terminal, keyboard works well, as on internet with chrome.

The 2nd app where i have issue, it's with Dolphin and the filter or the create directory box. None of them recognize letters i type. So they stay in their default status (empty or with "enter a directory name" if i use F10 key on the same keyboard)

What could be the issue as my keyboard works great... the proof is that i wrote this post with the same keyboard on the same laptop

thx

Some more details about your specific hardware as well as you settings in the System Settings -> Hardware -> Input Devices ->Keyboard settings might be helpful, specifically whether you chose a specific model and if you use a particular layout

All settings are since KUbuntu 16.04 so till now it worked (so till i upgrade to KDE Ubuntu 20.10).
I do not understand what could be the reason why it stopped to work on some apps.

I use 3 different layouts and i switch between them using Alt+Shift

here are the other information:





here it's a place where keyboard is not working anymore:


Here is my info center screen:


I have 3 different DE installed : KDE, Gnome and Deepin.

I realized that after removing Deeping, main menu search box works again. I will confirm it in few days if everything still works.

it's now 2 days since i removed Deepin DE and my keyboard works very well. So i guess we can say that Deepin DE (even it's not active DE) impacted on KDE features.

might be a good idea to file a bug against it, then.

Ok, so problem is back even if i use original laptop keyboard. So it has nothing to do with wireless keyboard or with Deepin DE.

Problem is located somewhere else.

Bug ticket opened in tracking system of KDE

Could you please give a link to the bug report here as well?
